Work or play
I've had an HTC Desire for a month and it is a great toy, but it's a real struggle to use it for work. Synchronisation with Outlook is extremely unreliable (not just me, look at the forums). No matter, I'm told, I can ditch Outlook and use Google Calendar, which I can only update on my PC if I have a working net connection and which might not keep my information secret.
Apart from that, Android's personal information management (calendar and tasks) is poor out of the box. I can't put shortcuts to my colleague's work and mobile phone numbers on my home screen because they would both come up with the same name and picture, and they can't be individually changed. And often it won't switch off without taking the battery out.
Still, it runs Google Sky. That quite often tells me the sun is way above the horizon at midnght in London, but switching off the phone (taking the battery out if necessary) and switching on again usually brings it back to reasonable accuracy.
My 8 year old Palm M505 was boring but it synchronised reliably, it had precise text entry with the stylus, and I could read the screen in full sunlight. Compared to that, the Desire is infuriating. It does lots of wonderful things, but if only it did the basics really solidly!
